MODE OF SIZING PAPER.

Specification of Letters Patent No. 1,276, dated August 3, 1839.

To all whom it may conc-em 7e it known that We, WILLIAM IV. TIL- soN and CHARLES DICKERMAN, of W'estield, in the county of Hampden and State of Massachusetts, have invented a new and use ful Improvement in Machines for Sizing Paper,.which we denominate a Rotary Sizing- Machine, and we do hereby declare that the following is a full and exact description thereof.

In the accompanying drawing, A, A, is the vat within which the sizing liquor is to be contained, which liquor is to be prepared and managed in the ordinary way. From the center of this vat is to rise a vertical shaft B, which may rest on a step on the bottom of the vat, or on a standard C, attached to the bot-tom, and rising above the sizing liquor. The upper end of this shaft has a gudgeon which revolves in a suitable bearing.

D, D, are two circular disks, attached to the shaft, and having uprights E, E, E, eX- tending from one to the other near their peripheries, which uprights are fastened to the disks. Against each of these uprights there is a sliding piece F, to which the upright serves as a guide, as it slides up and down in a mortise in the lower disk. From the upper ends of these slides a cord passes over a pulley in the upright, and sustains a weight which acts as a counterpoise to the slide and its load, as shown in the drawing. At the lower ends of each of these slides there is a clamp G, for holding` the paper to be sized; this clamp may be opened and closed by means of a screw, or by any analogous device.

In using this apparatus it will be seen that the workman employed in sizing' the paper may dip all the respective portions successively without moving' from his station, by merely causing the shaft and its appendages to revolve, in consequence of which arrangement a much larger quantity of work may be performed than by the ordinary apparatus.

IVe do not claim to be the first who have used slides and clamps, such as we. have (lescribed, for the purpose of sizing paper; but

That we do claim as our invention, and desire to secure by Letters Patent, is

The placing of such slides in such a manner as that they may be carried around by a revolving shaft, in an apparatus contructed substantially in the manner, and for the the purpose, herein set fort-h.
